PRESS.

SPECIFICATIONformingpart of Letters Patent No. 225,122, dated March 2,1880.

Application filed January 6, 1880.

To all whom it may concern Be it known that I, RALPH E. HAMILTON, ofRoyal Oak, in the county of Oakland and State of Michigan, have inventeda new and valuable Improvement in Presses; and I do hereby declare thatthe following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of myimproved press. Fig. 2 is a bottom view of the same. Fig. 3 is a topview of the follower, and Fig. 4 is a detail.

This invention has for its object the improvement of machines forexpressing cider, pressing cheeses, and other objects; and the nature ofthe invention consists in the novel construction and arrangement of thepress,

whereby very useful and desirable advantages are attained, as will behereinafter more fully set forth.

In the annexed drawings, the letter A designates the base or platform ofmy improved press, the same being strongly constructed, and, if desired,raised upon suitable legs. B indicates the driving-shaft, arranged inbearings in the sills or cross-beams of the platform, and provided withtwo spaced worms, to a. These worms mesh into the gear-wheels b 1;, uponthe lower endsof the follower-screws O O, and when the shaft B isrotated impart rotary motion thereto.

The shafts O C have their hearings in a longitudinal sill, c, of theframe, and upright metallic posts cl, erected on the platform, beingmaintained against downward displacement by a nut, 12, applied thereonand bearing against the upper ends of the said posts, as shown in Fig.l. A' washer, i, is interposed between the said nuts and the posts toprevent binding and undue friction.

D indicates the follower, composed of the strong central wooden beam, 6,two or more strong cleats, f, at right anglesto the beam 6, and notchedupon their under sides at g to pass over the said beam, and two or moreplates, h, secured to the cleats f at each side of the beam 6, withtheir lower surfaces flush-with that of said beam 6'. The plates h areshorter than this beam, and are bolted to the cleats, the latter beingalso bolted to the beam. This then rigidly attached to the other end ofthe beam aforesaid.

z" indicates nuts recessed into the ends of beam 6, and secured inposition in any suitable manner. The follower screws 0 0 pass throughthese nuts i, so that when the driving-shaft is actuated the followerwill be run up or down, as the case may be. This shaft B may be operatedby means of a crank, or by other equivalent means.

Sometimes, if I so elect, the follower-screws may beone right and theother left handed, and instead of the gears and worms I may usebevel-gear.

J indicates a horizontally rotating or vibrating table or platform, thesame being of rectangular form, usually with rounded corners. This tablehas a central perforation, 1;, through which the post d projects andextends an equal distance each side of said post. It also rests with thewhole length on the platform, one half being under the follower and theother outside of the press. The object-say a cheese or cheeses to bepressedis placed on the table under the follower and the latter rundown. While the pressure is going on one or more cheeses are placed onthe other end of the table, the follower run up, and pressure beingfinished, the said table is turned about the post end'for end, thusbringing the second cheese or cheeses under the follower, and greatlyeconomizing time and labor.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with the platform A, the follower-screws O G, and amechanism actuating the same simultaneously, of the follower D,consisting of the beam 0, having nuts i in its ends to receive saidscrews, the transverse cleats f, plates h, and truss-rods Z,substantially as specified.

In testimony that I claim the above 1 have hereunto subscribed my namein the presence of two witnesses.

RALPH EDWIN HAMILTON.
